          大于 3.8;其线性范围分别为 4.9~486.0、4.9~488.5、4.5~451.5、6.8~683.5、5.2~525.0、5.2~520.0 ng/mL(r≥0.999 8),定量限分
          别为 4.86、4.88、4.52、6.84、5.25、5.20 ng/mL,检测限分别为 0.97、0.98、0.90、1.37、1.05、1.04 ng/mL,重复性试验的 RSD 为 2.2%~
          5.6%(n=6),精密度试验的RSD为0.5%~1.4%(n=6),稳定性试验的RSD为1.5%~3.4%(n=5),低、中、高质量浓度回收率溶液
          的平均加样回收率为83.4%~103.0%(RSD为1.2%~6.3%,n=3)。在氯沙坦钾原料药及其制剂中均未检出6种N-亚硝胺类基因毒性
          杂质。结论  该法分离效果好、准确性高、灵敏、简便,可用于氯沙坦钾原料药及其制剂中6种N-亚硝胺类基因毒性杂质的检测。

          ABSTRACT    OBJECTIVE  To  establish  a  method  for  simultaneous  determination  of  the  contents  of  6  kinds  of  N-nitrosamines
          genotoxic  impurities  in  losartan  potassium  raw  material  and  its  formulations.  METHODS  GC-MS/MS  was  adopted  to  determine  6
          kinds  of  N-nitrosamines  genotoxic  impurities  in  losartan  potassium  raw  material,  Losartan  potassium  tablet,  Losartan  potassium
          capsule  and  Losartan  potassium  hydrochlorothiazide  tablets,  such  as  N-nitrosodimethylamine (NDMA),  N-nitrosodiethylamine
         (NDEA),  N-ethyl-N-nitroso-2-propanamine (NEiPA),  N-nitrosodiisopropylamine (NDiPA),  N-nitrosodipropylamine (NDPA)  and
          N-nitrosodibutylamine (NDBA).  The  separation  was  performed  on  SHIMADZU  SH-L-17Sil  MS  capillary  column  by  temperature-
          programmed  GC,  with  injector  temperature  of  250  ℃,  sample  size  of  1  μL,  carrier  gas  of  helium,  and  carrier  flow  rate  of  1
          mL/min.  Electron  ionization  and  multiple  reaction  monitoring (MRM)  data  acquisition  mode  were  used,  with  an  ion  source
          temperature  of  250  ℃  and  solvent  delay  time  of  3.1  min.  RESULTS  The  separation  among  NDMA,  NDEA,  NEiPA,  NDiPA,
          NDPA,  NDBA  and  adjacent  chromatographic  peaks  was  good,  and  the  separation  rate  was  higher  than  3.8;  the  linear  ranges  of
          them  were  4.9-486.0,  4.9-488.5,  4.5-451.5,  6.8-683.5,  5.2-525.0  and  5.2-520.0  ng/mL(all  r≥0.999  8). The  limits  of  quantitation
          were  4.86,  4.88,  4.52,  6.84,  5.25  and  5.20  ng/mL;  the  limits  of  detection  were  0.97,  0.98,  0.90,  1.37,  1.05  and  1.04  ng/mL.
          RSDs  of  repeatability  tests  were  2.2%-5.6%(n=6),  those  of  precision  tests  were  0.5%-1.4%(n=6),  and  those  of  stability  tests
                                                              were  1.5%-3.4%(n=5),  respectively.  Average  recoveries  of
